President Volodymyr Zelensky has renewed his calls for the Prime Minister to send fighter jets to Ukraine, one year on from Russia’s invasion.
During a press conference on Friday he asked a British journalist “Where are our typhoon aircraft?” and followed with “Please ask my friend Rishi [Sunak]”.
During the conference he also said the worst moment since the war began was the Bucha massacre, when hundreds of civilians were killed by Putin’s troops.
“What I saw there. The moment we de-occupied Bucha, it was horrible. What we have seen - the devil is among us,” he told journalists.
Mr Zelensky’s reflections came as Rishi Sunak agreed with G7 leaders to intensify military aid for Ukraine’s armed forces.
In a statement after meeting virtually they pledged to deepen sanctions against those aiding Russia's war effort.
Separately, Washington released details of new measures it was taking that not only targeted Russia but also "third-country actors" across Europe, Asia and the Middle East that are supporting Russia's war effort.
Britain also issued more sanctions against Russia, including export bans on every item it has used on the battlefield and import bans on iron and steel goods.
Mr Sunak led the UK in a minute’s silence at 11am from outside Downing St as the King issued a message praising the “remarkable courage and resilience” of Ukraine’s people.
Charles said in his message: “It has now been a year that the people of Ukraine have suffered unimaginably from an unprovoked full-scale attack on their nation. They have shown truly remarkable courage and resilience in the face of such human tragedy.”
